We have it installed in an Audi TT from 2001 with an adapter for 17 euros - available here. Although I have to potter about a bit, because Audi, for example, has placed no ignition plus the radio (at least not in the model that I had) but in the end I am pleased to hear beautiful sounds and the speakerphone is 1a. Since we have built in a roadster, we chose the microphone position on the steering wheel in the tacho - at 70 km / h open noted the interlocutor not mean that you just cruised through the area.
My model could be set only in English, which is no problem for me (instructions, incidentally, was also in EN) - the lighting fits well with the old Audi design.
Everything right for 88 Euro.
